ALBERT WILLIAM SNEDDEN, OF BROQKVILLE, PENNSYLVANIA.

Application filed February 15, 1924.

To all whom it viz-a3 concern.

Be it known that ALBERT W. SNEDDEN, a citizen of the United States, residing at Brookville, in the county of Jefferson and tate of Pennsylvania, has invented certain new and useful Improvements in Fuse Holders, of which the following is a specification.

This invention relates to a new and useful improvement in fuse holders and has for its principal object to provide asimple and efficient device which will hold a fuse in a cap wherein is contained the charge of explosive to ignite the fuse in such a manner as to prevent any possibility of danger in the handling of the same.

Another important object of the invention is to provide a fuse holder of the above mentioned character, which is of such aconstruction as to enable the several parts comprising the same to be readily assembled or disassembled without employing any tools, thus furthermore insuring safety in the handling of the fuse while preparing the same 101' use.

A still further object of the invention is to provide a fuse holder wherein means is provided for securely holding the fuse in the cap containing the charge of an explosive and additional means is provided to prevent the fuse and the charge in the cap from becoming damaged by water which would consequently result in the loss of the fuse and also cause unnecessary expenses.

A still further object of the invention is to provide a fuse holder of the above mentioned character, which is simple in construction, inexpensive, strong and durable and further well adapted for the purposes for which it is designed.

Other objects and advantages of this in vention will become apparent during the course of the following description.

In the accompanying drawings forming a part of the specification, and in which like numerals designate like parts throughout the same.

Figure 1 is a side elevation of my fuse holder showing the same assembled and in position for use.

Figure 2 is a longitudinal section thereof.

Figure 3 is a detail view of the several parts of my invention, and

Figure 4 is atransverse section taken on lines 4l 1 of Figure 2 looking in the direction of the arrows.

In the drawings wherein for the purpose Serial No. 693,067.

of illustration is shown the preferred embodiment of my invention, the numeral 1 designates an elongated cap which is formed of any suitable metallic material and has its inner end closed shown at 2 in the drawings for the purpose of providing a means for holding the charge of explosive which may be of such a character as commonly used and preferably I desire to use fulininate of mercury, and this charge is designated by the numeral 3 in Figure 2 of the drawings. Formed at the open end of the cap 1 is the annular flange the purpose of which will hereinafter be more fully described. The cap is furthermore provided with internal threads as shown at 5 in the drawings adjacent the open end thereof for the purpose of locking the fuse holder hereinafter described within the cap.

The fuse holder above referred to comprises the sleeve 6 and which is of a diameter slightly less than the diameter of the cap 1 and this sleeve is provded with an annular flange 7 at its outer end as clearly shown in Figures 2 and 3 of the drawings the flange 7 being of the same diameter as he flange 4 formed on the cap 1. The sleeve 6 is also provided with the external threads 8 which are formed adjacent the annular flange '7 and are adapted to cooperate with the internal threads 5 provided on the cap 1.

To facilitate the easy and ready insertion of the fuse A within the sleeve 6, I provide the outer end of the sleeve with diametrically opposed slits 9 the latter extending longItudinally for a suitable distance from the outer end of the sleeve in the manner as clearly shown in Figure 3 of the drawings. Ihns the sleeve will be provided with spring jaws which may be readily placed around the fuse A adjacent the inner end thereof and to further hold the fuse A in proper positlon within the slitted sleeve I provide the spurs 10, the spurs being formed on the inner wall of the sleeve and arranged adjacent the annular fiange thereon whereby the same will bite into tne fuse and hold the same against longitudinal movement within the sleeve when the same is in position for use.

In assembling my fuse holder, the fuse A is placed within the sleeve 6 so that the inner end of the fuse will extend for a substantial distance beyond the inner end of the sleeve. The spring jaws of the sleeve I senate haid tiiei the by d pre s -age :tiie :interna th Ew n E as :descaibed any: invent i; fuse holder: 201: the class .engated :ea

As the operation of the charge igniting and fuse igniting is well known in the art it is not thought necessary to further go into detail as to this particular feature. It be ing sufiicient to state that the outer end of the fuse A is connected to the dynamite to be exploded in the well known manner.

It will thus be seen from the foregoing description, that a fuse holder has been provided which is of such a construction as to permit the same to be readily disassembled or assembled in a simple and efficient manner and which will furthermore securely hold the fuse in the proper supported position within the cap containing the charge of explosive and will at all times permit a person to handle the same without any danger of becoming injured.

From the foregoing description of the construction of my improved apparatus, it will be seen that I have provided a simple,

understood that the sleeve ope cap, tending into said cap and removably secured therein, a fuse fitting in said sleeve and havingits inner end extending in close proximity to said charge, and a flanged rubber gasket carried by the open end of said cap and having its flanged portion interposed between the aforesaid flanges.

4. A fuse holder of the class described comprising an elongated cap adapted to hold a charge of explosive in the closed end thereof, an annular flange formed on the outer end of said cap, said cap being internally threaded adjacent the outer end thereof, a sleeve having an annular flange formed on the outer end thereof, said sleeve being externally threaded adjacent its annular flange for securing the same in the open end of said cap, a fuse carried by said sleeve and having its inner end extending within said cap in close proximity to said charge of explosive, and a rubber gasket carried by said cap and having a collar formed thereon at its outer end, said collar being adapted to be interposed between said annular flanges. In testimony whereof I affix my signature ALBERT VILLIAM SNEDDEN.
